This is a wordsearch puzzle solver. I know this is not the most efficient solution to solving a wordsearch. Using tries is much more efficient than this brute force solution. My purpose for this program was to demonstrate my knowledge of hashtables in C++ and the unordered_set is one such implementation in the C++ STL.
